I just got a 3412 pvr yesterday. The remote has the jp1 connectors but is is not compatible. There are several codes that will set up the remote.
I.E. 993-volume lock, 993, 973, 992, etc. I have found using 994 (undocumented) that I can remap keys to any key of the same device using the efc code. Does anybody know of any other codes that are undocumented? I would like to program a couple of macros -like on the ALL-ON button that is a macro button. Thanks for the info, Doug_________________thanks, just4fn

I'm not sure anybody has listed all of the 3-digit "magic" codes there are. Unfortunately, only certain subsets of all of them work on certain remotes, and I don't know that there is any consistency as to which sets are available on which remotes. The only place I know of these codes is in Rob's individual tailored manuals, so you could go scouring through them and test out each one.
